* armvirt/64: change it to cortex-a53 instead of genericJosef Schlehofer2020-12-141-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Package architecture aarch64_generic [1] can be used just with three devices. One is NanoPI R2S and then there are two development boards from NXP. Let's change armvirt/64 to Cortex A53 (aarch64_cortex-a53) [2]. It has wider support by multiple devices like NanoPI Neo Plus2/Core2, ESPRESSObin, Pine64, and Raspberry Pi 2&3. While looking at ARMvirt/32 it has set CPU_TYPE and CPU_SUBTYPE to be arm_cortex-a15_neon-vfpv4 [3]. It has support to devices like Linksys EA8500 v1, Linksys EA7500 v1, Netgear D7800, Netgear R7500 and so on. Tested with: qemu-system-aarch64 -m 1024 -smp 2 -cpu cortex-a57 -M virt -nographic \ -kernel openwrt-armvirt-64-Image-initramfs Successfully compiled and booted.

* kernel: remove support for kernel 4.19Adrian Schmutzler2020-10-301-230/+0
| | | | | | | We use 5.4 on all targets by default, and 4.19 has never been released in a stable version. There is no reason to keep it. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
* kernel: Move CONFIG_IONIC to generic kernel configHauke Mehrtens2020-08-101-1/+0
| | | | | | | It is deactivated everywhere, just set this in the generic config. Acked-by: Yousong Zhou <yszhou4tech@gmail.com> Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
* kernel: move TEO governor to generic configTomasz Maciej Nowak2020-03-171-1/+0
| | | | | | | | This new symbol popped up in few places. Disable it in generic config. Signed-off-by: Tomasz Maciej Nowak <tomek_n@o2.pl> [fixed merge conflict in generic/config-5.4] Signed-off-by: Petr Štetiar <ynezz@true.cz>
* armvirt: Remove kernel 4.14 supportHauke Mehrtens2020-03-121-179/+0
| | | | | | | | | | This target was switched to kernel 4.19 more than 6 months ago in commit f342ffd300da ("treewide: kernel: bump some targets to 4.19") and now with kernel 5.4 support being added it gets harder to support kernel 4.14 in addition to kernel 4.19 and 5.4.

* armvirt: refresh 4.19 kernel configPetr Štetiar2019-06-181-44/+95
| | | | | | | Refresh kernel configs with 4.19 bits, while at it, add common symbols into the target config. Signed-off-by: Petr Štetiar <ynezz@true.cz>
* armvirt: add kernel configs for 4.19Petr Štetiar2019-06-182-0/+179
| | | | | | | It's just copy of 4.14 and will be refreshed in the upcoming commit, renamed config-default to config-4.14 as well. Signed-off-by: Petr Štetiar <ynezz@true.cz>
* kernel: Remove CONFIG_COMPATHauke Mehrtens2019-05-111-10/+0
| | | | | | | | | | | | | This removes support for executing old 32 bit applications on 64 bit ARM and MIPS kernels. On OpenWrt we normally compile all the user space applications on our own and do not support third party binary only modules especial not 32 bit applications on 64 bit CPUs. This reduces the attack surface on such systems and should also save some memory. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
* kernel: Activate CONFIG_ARM64_SW_TTBR0_PANHauke Mehrtens2019-05-111-1/+0
| | | | | | | | | | This activates "Emulate Privileged Access Never using TTBR0_EL1 switching" on ARM64. This should prevent the kernel from reading code from user space in kernel context. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
* armvirt64: enable qemu drm driversLucian Cristian2019-04-181-0/+4

* kernel: add missing ARM64_SSBD symbolStijn Tintel2018-07-311-0/+1
| | | | | | | | | In 4.14.57, a new symbol for Spectre v4 mitigation was introduced for ARM64. Add this symbol to all ARM64 targets using kernel 4.14. This mitigates CVE-2018-3639 on ARM64. Signed-off-by: Stijn Tintel <stijn@linux-ipv6.be>
* arm64: enable harden branch predictorMathias Kresin2018-04-271-0/+2

* kernel: move CONFIG_KASAN to generic configStijn Tintel2018-01-021-1/+0
| | | | | | | | | | While bumping 4.14, the kernel build failed due to missing CONFIG_KASAN symbol. Move it to generic config instead of defining it for all arm64 and x86/64 targets. It was only added in 4.0, so not needed in config-3.18. Signed-off-by: Stijn Tintel <stijn@linux-ipv6.be>
* armvirt: Enable CONFIG_ARM_PMUFlorian Fainelli2017-09-161-0/+1

* armvirt: merge arm64 as subtarget 64Yousong Zhou2017-04-232-0/+178
Original armvirt target is now subtarget 32. Other than that the built result should remain the same as before Besides old features already available with arm64, the new armvirt/64 subtarget will also have those features originally enabled for armvirt/32 with commit 44ecfc2 ("armvirt: new target") - pl011, uart - pl031, rtc - pl061, gpio - pci-host-generic - virtio_{mmio,pci,net,blk,scsi,9p,console,balloon} - smp with NR_CPUS=4 - cpu-hotplug - ext4 - DEBUG_BUGVERBOSE for debug purposes Signed-off-by: Yousong Zhou <yszhou4tech@gmail.com>
